Application August 24 1945, Serial No. 612,363 1 Claim. (Cl. -210) This invention relates to new and useful improvements in dip stick cleaners.

The primary object of my invention is to provide a novel device of. this character, whereby the dip stick may be thoroughly cleaned by the gas station attendant or operator before inserting same in the crank case of the automobileengine or other motor to determine the level of the oil, by a simple operation.

A further object of my invention isto provide a cleaning device of the character specified that is simple and economical in construction and highly efficient and durable in use.

With the foregoing and other objects in view that will appear as the nature of my invention is better understood, the same consists in the novel features of construction, combination and arrangementof parts illustrated in the accompanying drawings and more particularly pointed out in the appended claim.

In the accompanying drawings, which are for illusrative purposes only and are therefore not drawn to scale:

Figure 1 is a side elevation of a dip stick cleaner, constructed in accordance with my invention.

Figure 2 is a vertical longitudinal section, taken on line 2-2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is a similar. view, taken on line 3-3 of Figure 2, looking in the direction indicated by the arrows.

Figure 4 is a top plan View.

Figure 5 is a bottom plan view.

Figure 6 is a detail edge view of the base and steel spring strips which support the wiper sleeves, removed from the tube.

Referring to the drawings for a more particular description of my invention, and in which drawings like parts are designated by like reference characters throughout the several views, A

designates my improved dip stick cleaner, as a whole, which is designed for use in connection with the dip stick used for measuring the oil level in the crank case of passenger cars, trucks, busses or tractors. The cleaner Amay be mounted under the hood of the motor, or other convenient location, by universal brackets or other equivalent means.

Specifically, my cleaning device comprises the cylindrical metal tube I, formed in its top 2 and in opposite sides, with the corresponding vertical longitudinally disposed slots 3, which extend throughout the greater portion of the length of said tube, andthe purpose of which will presently appear.

.5 gradual curve, but

Two'corresponding strips or pieces 4 of spring steel approximately three inches in length, are

Welded or otherwise rigidly mounted on a fiat circular base 5, which bottom of the tube l. The aforesaid strips 4 are completely covered or encased in the sleeves 6, of cloth, felt, or other suitable material, and said sleeves are open at their lower ends, as at I, and bound together and closed at their upper ends by the wire 8. As shown, the cloth or felt sleeves 6 are applied by inserting their lower ends over the upper ends of the strips 4.

In carrying out my invention, the spring steel strips 4 are bent upwardly and outwardly on a when inserted in normal or operative position in the tube I, the upper ends of these cloth or felt covered strips fit against the inner faces and opposite sides of the slotted upper end of the tube and press the inner faces of the cloth or felt sleeves 6 together at the desired tension.

In practice, the dip stick is cleaned by the gas If desired, the dip stick may be inserted endinto the slotted tube. l instead Wise downwardly of cross-wise.

Attention is invited to the fact that the lower ends of the strips 4 are welded or otherwise fastened to the circular base 5 in such a way that a central passage or opening 9 is formed to allow any surplus oil to flow or escape from thebottom of the tube.

The use of my invention will save valuable time of the station attendant or operator and eliminate the necessity of constantly washing his clothes on which the dip stick is ordinarily cleaned.

From the foregoing description taken in connection with the drawings, it is thought that the construction, operation and advantages of my invention will be readily understood, without requiring a more extended explanation.

Having described my invention, what Iclaim as new and desire to'secure by Letters Patent, is:

In a dip stick cleaner of the character specified, a longitudinally slotted tube and a cleaning element removably mounted in said slotted tube,

fits against the lower end or wise through the slotted said cleaning element comprising a pair of corresponding longitudinally disposed fabric covered steel spring strips pressed together at the desired tension, but adapted to be spread apart against such'tension when the dip stick is drawn crossportion of the tube to clean the former and a circular base to which the lower ends of said strips are attached, said base adapted to fit against the lower end of the slotted tube.

1 KENNETH NIELSEN.
